In this paper the numerical method for solution of an
aeroelastic model describing the interactions of air flow with vocal folds is
described. The flow is modelled by the incompressible Navier-Stokes
equations spatially discretized with the aid of the stabilized finite element method.
The motion of the computational domain is treated with the aid of the Arbitrary
Lagrangian Eulerian method. The structure dynamics is replaced by a mechanically equivalent system
with the two degrees of freedom governed by a system of ordinary
differential equations and discretized in time with the aid of an implicit multistep method and strongly coupled with
the flow model. The influence of inlet/outlet boundary conditions is studied
and the numerical analysis is performed and compared to the related results from literature.
